FRANK D. WINKLEY, 0F MADISON, WISCONSIN, ASSIGNOR 'IO MADISON-K115?LUBRI- CATOR COMPANY, OF MADISON, WISCONSIN, A CORPORATION OF WISCONSIN.

LUBRICATOR.

To all whom it may concern:

Be it known that I, FRANK D. WINKLEI, a citizen of the United States,residing at Madison, in the county of Dane and State of Wisconsin, haveinvented a certain new and useful Improvement in Lubricators, of whichthe following is a specification.

My present invention pertains to force feed lubricators and hasreference more particularly to the provision of means for adjusting andcontrolling the flow of oil, the means being such as to prevent theparts from being brought into such position as will cut down the amountof oil fed below a predetermined minimum, while at the same timeallowing free adjustment for a greater flow or feed.

In the use of force feed lubricators upon machines, and more especiallyupon automobiles, where adjustment of the parts frequently falls intoinexperienced hands, there is a possibility of the user adjusting thelubricator so as to cut off the oil-supply, or reduce it to a pointbelow which it will not effectively lubricate the parts to which the oilpasses.

It is the object of this invention to provide an inaccessible,adjustable lock or stop for the feed-controlling means of thelubricator, which lock may be initially set by one skilled in the art oflubrication, and which, while permitting adjustment for greater feed,will prevent such adjustment as would cut the feed down below theestablished minimum.

The invention is illustrated in conjunction with a lubricator of thetype set forth in Letters Patent No. 1,066,238, granted to me under dateof July 1, 1913.

In the drawings:

Figure 1 is a sectional elevation of so much of a lubricator as isnecessary to an understanding of the invention;

Fig. 2 a like view of the adjusting stem or rod, and the stop or lockingquill;

Fig. 3 a disassembled View of said parts; and

Fig. 4 a detail view showing the parts in a difi'erent adjustment fromthat illustrated in Fig. 1.

A suitable casing, as l, is provided in which the parts are mounted andinclosed, a sight window or cover 2 being placed over the upper end of atube or pipe 3 and the cup at into which the tubedischarges.

Specification of Letters Patent.

Patented May 21, 1918.

Application filed January 8, 1917. Serial No. 144,312.

Pipe 3 at its lower end is in communication with the cylinder 5 of ameasuring pump, while the tube 6, upon which cup 4 is mounted, is incommunication with the cylinder 7 of a force pump by which the oil isforced to the part or parts to be lubricated. Cylinder 7 is providedwith a piston or plunger 8, having connected to its upper end, by agimbal joint, a yoke 9. A strap 10 is swiveled in the yoke, said strapbeing in engagement with an eccentric 11, through which a driving shaft12 passes, this construction being similar to that disclosed in LettersPatent No. 796,659, dated August 8, Piston 8 also carries a sector gear13, which meshes with a similar shrouded gear 14:, secured to the upperend of the piston or plunger 15 of the measuring pump.

Through the rotation of shaft 12, the eccentric causes the strap andyoke to be raised and lowered and likewise imparts an oscillatingmovement to the yoke, which motions are transmitted to pistons 8 and 15through the intermeshing gears 13 and lt. As a consequence, said pistonsare raised and lowered and also oscillated, and inasmuch as they areprovided with suitable intake and delivery ports the oil will be drawnin by the measuring piston 15 and forced to the sight feed cup 1 andthence forced to the part to be lubricated, by piston 8.

To regulate the quantity of oil which may be drawn into the measuringpump or cylinder 5, a sleeve 16 extends upwardly into said cylinder, thesleeve surrounding piston 15 and operating in the manner set forth inPatent No. 1,066,238.

A laterally-extending arm 17 is rigidly secured to the lower end of saidsleeve 16, and an adjusting rod 18 extends through the arm, the partshaving a threaded engagement. The rod extends upwardly through thecasing and the outer end is preferably flattened for the application ofa spanner or wrench. The rod extends through a quill 19, which passesthrough a fixed member 20 of the lubricator frame, the quill having athreaded connection with said member, the pitch and direction of thethread being the same as that of the thread on rod 18. Stop collars 21and 22 are secured upon the rod and bear against the upper and lowerends, respectively, of the quill so that the rod may be said to beswiveled in the quill. A nut 23 is screwed upon the lower end of the rodand serves to limit the downward movement of the arm 17, and to preventthe rod from being screwed out of the same.

In adjusting the device prior to the placement of the cover of thecasing, the expert will turn the quill up or down, as the case may be,the rod 18 turning with it, without affecting the position of arm 17 andthe sleeve 16 as the rod turns in said arm. IVhen elevated to theposition shown in Fig. 1 the sleeve may be moved upwardly toaconsiderable extent in the cylinder, or until the arm 17 abuts the lowerend of the stop collar 22, beyond which it cannot move. This adjustmentwill allow a relatively small feed of oil by the measuring pump, andwhile such feed may be increased by turning the rod 18 to lower arm 17and the attached sleeve so as to increase the effective volume of thecylinder 5, it cannot be diminished beyond the fixed minimum.

In Fig. 1 the quill is shown in a lower position, and this would producea larger minimum flow than under the adjustment shown in Fig. 1. Underboth adjustments of the quill the feed of oil may be increased, but itcannot be cut down below the predetermined minimum.

v Inasmuch as the quill is inaccessible when Copies; of this patent maybe obtained for the cover is finally positioned, the inexperiencedoperator is precluded from varying the minimum amount ofoil to be pumpedto the part to be lubricated.

Having thus described my invention, what I claim is:

1. In a force feed'lubricator,,the combination of a casing; a pumplocated therein;

a sleeve adjustably mounted in the pump to 2. In a force feedlubricator,the combination of a measuring pump; a forcing pump; gearing connectingthe pistons of said pumps to cause them to oscillate in unison; a powerdevice to actuate said gears and to raise and lower the pistons; andmeans for controlling the capacity of the measuring pump.

In testimony whereof I have signed my name to th1s specification.
